The Lowdown
Alright, Rusty here, let’s break down Jaconé in feet and degrees.
We’ve got a slow start with no real surf to speak of for several days. From Sunday the 16th through to around Thursday the 20th, it’s mostly flat or tiny. The water is about 73°F, which is normal for this time of year.
Monday morning 17th – Waves around 4ft from the south, period about 11 seconds. Offshore wind from the ENE at 15 mph, so clean, but it’s weak with combined energy at 450. Not worth the drive.
Tuesday morning 18th – Waist-high 4ft from the east-northeast, period only 7 seconds. Light offshore from the NE at 9 mph, clean but ordinary. Energy is low (310).
Wednesday 19th – Drops to 3ft from the east, period short. Light offshore in the morning. Combined energy is a paltry 80. Barely surfable.
Thursday 20th – Morning is flat. 2ft from the east, period 8 seconds, glassy. Energy 49. Stay home.
Friday morning 21st – Best of the first week. 4ft from the east-northeast, period 7 seconds, with a light offshore from the north-northeast at 6 mph. Combined energy is 255. Clean, small, but workable.
The real standout is Sunday morning 23rd of August. This is the day. Swell is 5ft from the south-southwest, period 12 seconds – proper groundswell. Combined energy is a solid 712. And the wind? Dead calm, glassy. This is the cleanest, most fun day of the whole outlook. Get out early.
Monday 24th – Swell builds to 7ft from the south-southwest, period still 12 seconds, but the wind turns onshore from the SSE at 9 mph. Choppy and cross-onshore. Energy is 1279, but the quality suffers.
Tuesday 25th – Big day for experts only. 8ft from the south, period 13 seconds, with an offshore from the NE at 12 mph in the morning. Combined energy is massive at 2545. This is powerful, clean, and only for experienced surfers.
Wednesday 26th – Swell holds at 8ft from the south with a long 14-second period, but onshore wind from the SW at 3–9 mph messes it up. Energy is 2228, but it’s blown out.
Thursday 27th – Drops to 5–6ft from the south, period 13 seconds, with light cross-shore winds from the SSE. Energy is around 1200. A bit bumpy, but might have some clean sets.
Friday morning 28th – Nice clean finish. 4ft from the south, period 11 seconds, with a gentle offshore from the ENE at 9 mph. Energy is 501. Clean and fun.
Saturday 29th & Sunday 30th – Back to small. The 30th has a 1ft swell in the morning, but a long-period 16-second swell shows up Sunday afternoon (3ft from the south, energy 505). Clean but tiny.
Monday 31st – Last day shows 5ft from the south, period 12 seconds, with a light cross-offshore wind in the morning. Energy is 736. Clean, decent end to the run.
Best bets: Sunday 23rd morning for glassy fun, and Tuesday 25th morning for big, clean, expert-only waves.
Catch you in the water.

Information about the Jaconé Surf forecast
The above surf forecast table for Jaconé provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Jaconé can be found by selecting the local surf guide option on the grey menu. Our Jaconé surf forecast is unique since it includes wave energy (power) that defines the real feel of the surf rather than just the height or the period. If you surf the same spot (Jaconé) regularly then make a mental note of the wave energy from the surf forecast table each time you go. Very soon you may start to choose your surf days based on the wave energy alone combined with our forecast of favourable offshore wind conditions. Our star ratings will help here and of course you will also find the usual wave height and period predictions on our surf forecasts as well as a full break down of the swell components under our advanced users option (to reveal that, click the little Einstein character under the tide times).
Further information to help with frequently asked questions about our surf forecast for Jaconé may be found under the help tab on the top menu and also by moving your mouse over the question marks on the surf forecast table itself. Please always bear in mind that the forecast is for near-shore open water and local factors at each surf break influence the actual breaking wave height, such as the beach / reef profile, water depths offshore and shelter.
